How much should it cost to replace a timing belt?

My car has been making this squealing noise and people are telling me it's my timing belt. I have to take it to the mechanic, but I'm a girl and I want to know what a reasonable price is so I don't get ripped off; I know how these mechanics get when they see a girl come in.

I have a Toyota Matrix XR 2003 and I have 120k miles on it.

Thanks for your help!

Need urgent advice on how to remove old CV joint ion a 1996 Mitsubishi Magna Executive 5 speed manual?

HI out there!
Having a heel of a time removing an old left front CV/ driveshaft from the old Magna-totally shot. 5 speed manual gearbox.
Have got as far as removing the shaft and CV boot, gearbox end stuck inside gearbox. Shaft has totally come off. Do we have to remove right axle to get left one out (don't really want to do that, as right one is damaged as well, can't afford both at same time!) or do we just keep banging away at the end left in the gearbox until it releases? We have tried turning it to\n try and help release it whilst prying it out, no good. still stuck.
ANY advice much appreciated!

Opinions on whether or not my car be fixed?

I was recently in a car accident & my car (a 2003 Honda CR-V) had to be towed away. The engine was untouched, the front/side needs some body work, but what I'm most worried about is that both of the front airbags deployed. There's at least 120,000 miles on the car. It's been good to me & I'm really hoping that it's repairable. Any expert opinions?

Should I replace my radiator?

My cars a four cylinders like many four cylinder I have noticed the engine temperature always sits in the middle. Maybe im just over thinking but my engine temperature during a long shift of delivering pizzas in a blocked city half the time goes a niche, a quarter of a centimeter over the middle, and then goes a niche under, and then sits in the middle but im saying its as long as these dots are "…" at most, one a margin off "…………..l……………" the l being were it should be the other three dots the radius.

I was thinking degrease the engine or replace the radiator i know what could come next a head gasket and i already had that happen to me one lost a lot of money on a ford. The car i have now is a 97 cavalier really low miles if that helps your suggestion on what i should do if do anything thanks i appreciate anything.
